To all whom it may concern:

Be it known that I, FRANK W, MCLEAN,

I citizen of the United States, residing at Morenci, in the county of Greenle'e and State of Arizona, have invented certain new and useful Im rovenients in Automatic Counting and ecording Mechanisms, of which the following is a specification,

My invention relates to counting and registermg mechanismand particulan'l to mechanism designed for the purpose 0 re istering the passage of a car moving either in a vertical or a'horizontal direction.

' The primary object of my invention is,

the provision of a mechanism for the purpose of registeringthe passage of the skip or cage in a mine s aft, and a further obyect in this connection is to provide mechanism registering the movements of the skip or cage with relation to the time during which upward and the mechanism illustrated in Fig. 3; Fig. 5 is an the cage or car is movin time that the cage or car is at rest.

'A further object of the invention is to provide means for according and thereby counting the. number of trips made by a skip, cage or elevator car and in this connection to provide means for reg1ster1ng 1n a distinct manner every tenth trip of the car or cage so that the total number of trips made by the car between certain hours may be easily calculated.

A further object of the invention is to provide in connection with mechanism for recording the number of trips made by a cage or car within a certain definite period, a mechanism recording the distance traversed by the car to various levels, the time of said trips and the periods of time during which the car or cage lay idle.

A further object is to provide means whereby the trip registerin mechanism may be used for the purpose'o registering the number of cars'passing a certain point- A still further object is to provide in a mechanism of the character described, 2. cylinder adapted to receive thereon a recording strip upon which the record of the number of trips made by a car or cage may be regisp tered, provide a vertically movable sty operating over said strip, rovide means actuated by the movement 0 the car for causing a corresponding movement of the stylus,

and means actuatedbyla movement of the stylus for rotating certain amount a ter or-before one the car. 1

.theaii qording cylipder 2 o merely for the purpose of driving the s aft A further object in this connection is to provide an auxiliary stylus adapted to perform its function on every tenth trip of the icar which will indicate u on a recording ;st r1 said tenth trip there y topermit the tota number of trips'to be very easilycaliculated.

Other objects will appear in the course'of the following descri tion. 4 1 My invention is i'lustrated in the accompanying drawings wherein; A i Figure'l is an elevation of the upper end to! the hoisting mechanism of a mining cage for like elevator with in recording mechainism appl ed in conjunction therewith; Fig. 2 tsp perspective view of the recordin mechanism forming the subject matter 0 my inlvention; Fig. 3 is a side elevation of the recording mechanism looking toward the side pf the mechanism opposite to that illustrated iln F1g. "1; Fig. 4 isa top plan view of the end'elevation of the mechanism illustrated in Fig. 3; Fig. 6 is a fragmentary detail sectional view on the line 66 of Fig-5; F f7 18 a fragmentary detail elevation of one end of the styluscarrier broken away to show the means for yieldingly forcing out the lower stylus; Fig. 8 is a detail elevation pf a portion of a recording sheet showin the record made thereon; Fig. 9 is a detai perspective view of the member 78 looking from the insideto show the pawl in lace thereon; Fig. 10 is a side elevation the cam bar used in connection with the mechanism shown in Fig. 11; Fig. 11 is a erspecthe shaft 3 of this winding drum by means of .a sprocket chain 4 is a shaft 5 carrying thereon a worm 6 which engages with a inion or worm wheel 7 mounted on a shaft 8, this shaft in turn carrying a pinion 9 which meshes with a gear wheel 10 upon the shaft 11 on which there is mounted a pointer 12 moving over a dial 13, All these parts are of any usual or approved construction and form no, part of the subject matter of my invention, t e mechanism beingdesi ned 11 at a reduced speed but at a roper ratio to the shaft 3, so that as the ca le a on the winding drum A winds up or unwinds, the pointer 12 will indicate the various levels or floors to which the elevator, car, skip or cage has arrived. Mounted upon the shaft 11 is a wheel 14 which meshes with a rack bar 15 which in turn is connected in any suitable manner to a link 16 which at its 1 lower end is connected to a lifting rod 17.

Referring now to F' 2, 3, 4 and 5, it will be seen that the hfting rod 17 passes down between a pair of parallel vertical posts 18, these posts bein mounted at their 15 lower ends in a plate 19 w ich in turn is supported on posts 20 disposed at the four cornets of the plate 19 extending downward and engaging with a base plate 21 of any suitable construction. The post 20 is sur- 20 v rounded by sleeves 22 s acing the plate 19 from the base plate 21. he posts 18 at their upper ends pass through the horizontal arm 22 of an angular member 23 whose function will be later described. The upper ends of the post are threaded for engagement by nuts 24 and the member 22 is clamped down upon the upper ends of the posts 18 by means of these nuts 24 and is held rigidl in position. The member 22 is perforate at 25 for the passage of the actuating rod 17. Rotatably mounted upon the base plate 21 is a ratchet wheel 26 which may be. of

i any. suitable construction, and mounted upon the shaft of the ratchet wheel and 5 disposed upon the plate 19 is a gear wheel 27. Rotatably mounted upon the plate 19 is a cylinder 28 adapted to sup ort thereon a recording sheet, as will be ater stated. The base of this cylinder is rovided with gear teeth 29 which mesh wit the teeth of the gear wheel 27 so that as the ratchet wheel 26 is rotated the gear wheel 27 rotates the cylinder 28. It will be obvious that the motion of the ratchet wheel 26 is very much reduced before it is transmitted to the drum 28 so that a very slight movement of the cylinder 28 will correspond to a one-step movement of the ratchet wheel 26. The recording sheet 30 is supported in 0 place upon the cylinder 28 by means of the upper and lower bands 31 and 32, both of these bands bein constructed in the same manner and held 1n place by like mechanism. The cylinder 28 is hollow, and extending across the cylinder 28 are the upper and lower resilient rods 33 corresponding one to each hand. These rods are attached firmly to the inside face of the cylinder 28, as at 34, and at their other ends roject throughthe o elongated apertures 35 ormed in the wall of the cylinder 28. The extremities of the rods are annularly notched as at 36. At' one end of each of the apertures '35 there is disposed a clamp 37 which engages one end of as the corresponding band and which is pro-" vided with a tooth 37 engaging the slot 35.

the sheet 30 it is only necessary to retract the rods 33 which will loosen the bands, .whereupon the bands will be released and the clamp 37 will spring outward from the slot 35-permitting the sheet to be readily removed and replaced.

Mounted a ve the cylinder 28, in approximately axial alinement therewith, is a casing 39 containing spring-actuated clock mechanism or any other suitable motor designated 40. Th1s clock mechanism has a winding key 41 whereby the spring of the clock mechanism may be wound up and an arbor 42 which extends up through the easing and which is connected to a rotatable plate 43 having a downwardly extending flange 44. The plate 43 has arim 45 which extends over the flange 44 and is adapted to engage the upper edge of a recording sheet 46. This stn or sheet 46 is held in place by any suitab e means, but as shown for the purpose, the rim 44 has been provided with two downwardly extending resilient fingers 47 which gIrip the overlapped ends of the strip 46. he casing 39 is shown as supported by means of a bracket 48 which extends downward and is mounted upon the plate 19.

Supported upon the rods 18 as previously described is a member 23 angular in form so as to provide a transversely extending bar 22 and a laterally extending plate 49. The rod 17 asses through the transversely extending ar 22 and its lower end is connected to a slide or cross-head 50 formed with o nings 51 for the passage of the rods 18, w ich openings permit the slidin member 50 to shift up and down on and guided by the rods 18. Projecting from the end of the slide 50 which is adjacent the cylinder 28 is a stylus 52 which has an upwardly inclined extremity bifurcated to accommodate a thin-edged roller or wheel 53 which forms the stylus proper of the device. The slide 50 therefore constitutes a stylus carrier. The stylus 53 makes the record upon its recording sheet by superposing upon the record sheet a carbon sheet so that as the wheel 53 moves over the carbon sheet a mark will be left upon the recording sheet beneath. Inasmuch as the rod 17 moves up and down with each up and down movement of the elevator car, and as its distance of travel has a definite ratio with the elevator, cage or skip, it is obvious that the mark made upon the record sheet 30 will indicate wheel 26 and prevent the travel of the elevator. As will be apparent later on, only one vertical mark is made upon the recording sheet for each round trip of the skip or car.

Inasmuch as the rod 17 is the actuating rod and operatively connected to the car, it is obvious that some means must be provided for transmitting the movement 0 the rod 17 to the ratchet wheel 26 whereby the recording cylinder is shifted, it being of course necessary to shift the recording cylinder one step for each up and down movement of the skip, cage or car. For the purpose of securing this step by step movement of the cylinder 28 I provide the .following mechanism. Mounted in guides 54 just below the plate 19 is a reciprocatable pawl carrier designated 55, see Fig. 6. One end of this pawl carrier isreduced and passes through an opening in one of the guides 54, while the opposite end is reduced as at 56 and surrounded by a coil spring 57 which bears against the corresponding guide 54 so that the spring will retract the pawl carrier after each actuation. Mounted upon the pawl carrier is a pawl 58, see Fig. 6, which is forced against the ratchet teeth of the wheel 26 by means of a spring 59. The movement of the pawl away from the wheel 26 is limited by means of a sto screw 60. It will be obvious now that w en the awl carrier is shifted to the right, in Fig. 6, that the pawl-58 will engage with the teeth on the wheel 26 and will cause a forward movement of this wheel, and that upon a backward movement of the pawl carrier the pawl will escape pastthe tooth it was previously in engagement with and slip into the tooth just behind. The forward movement of the pawl carrier 55 and hence the amount of rotation given to the wheel 26 is limited by a pivoted stop pawl 61. This stop pawl 61 is pivoted intermediate its ends as at 62 in a supporting member 63 bolted to the base plate 21. The forward or tooth-engaging end of this awl is adapted to engage with the teeth 0 the an backward movement of the wheel 26. Tfie rear end of this pawl 61 is vertically widened, and passing through the rear end of the pawl is a stop screw 64 which is disposed in alinement with the reduced end 56 of the pawl carrier 55. As the pawl carrier moves forward it is obvious that the active end of pawl 61 will be moved outward against the force of a spring 65 and the outer end of the pawl will move toward the reduced end 56 of the pawl carrier. The end of the stop screw 64 and the end of the reduced portion 56 of the pawl carrier meet at the moment when the pawl carrier and its pawl have moved the wheel 26 forward one notch. At this point the awl carrier is allowed to slip backwar as will be later described, and-the pawl moves back one notch. As soon as the tooth has passed the active end of the pawl 61, the spring 65 will force the pawl back into engagement with the teeth. Below the pawl 61 is mounted a second pawl 66 which is forced into engagement with the teeth 26 by means of a spring 67. This pawl 66 acts upon the tooth in advance of the tooth acted upon by the pawl 61. It will thus be seen that upon each reciprocation of the sliding pawl carrier 65.the wheel 26 will be moved forward one step or notch, and the wheel 26 will cause the moving forward of the cylinder 28 a certain relatively small distance. Thus with each reciprocation of the rod 17 the slide 50 will be reciprocated and before such reciprocation has been accomplished the cylinder will have moved forward to bring a fresh portion of the rec 0rd sheet in front of the stylus 53.

The means for accomplishing the reciprocation of the pawl carrying bar 55 is as follows. The outer end of the slide 50 is laterally enlarged, as at 68, see Figs. 2 and 4, and resting against the face of this enlarged portion 68 is a flat bar 69 which bar extends downward and at its lower end is widened and provided with the outwardly projecting lug 70 the upper end of which is rounded or eveled. Resting against the face of this bar 69 is a flat bar 71 which at its upper end extends over the upper end of the bar 69, as at 72 see Fig. 2, and at its lower end is thickened so as to extend under the lower end of the bar 69, as at 73, and is extended downward and then widened as at 74, this widened portion 74 bein connected to the relatively narrow rod 71 by means of an inclined face 75 forming a cam which engages with a roller 76 carried in a longitudinal slot 77 formed in the pawl carrier 55. It will be seen now that upon each vertical movement of the rod 71 the inclined face 75 will come in contact with the roller 76 and will force the pawl carrier 55 laterally and cause the pawl to advance the wheel 26 one step. This advancing action of the rod 71 is intended to occur only on the initial. movement of the slide 50 from any position in which it may be, and the downward movement of the rod 71 and the cam 74 will occur upon the initial downward movement of the slide 50. The reason for this is that the rod 17 and the slide 50 will raise or lower a distance depending upon the amount of vertical movement of the cage or car. This distance will vary as the car falls or rises a greater or less distance, but the distance traversed by the wheel 26 upon each reciprocation either partially or fully of the rod 17 will be the'same under all circumstances, as it is only necessary to advance the recording cylinder 28 one step upon either a partial or a full reciprocation of the rod 17.

In order to secure a single forward step of the wheel 26 on each partial or full reciprocation of the rod 17, I have provided for a sliding engagement between the end face of the slide 50 and the rods 69 and 71. In order to hold these rods in engagement with the face of the slide 50 I provide a bridge piece designated 78 which 15 formed as illustrated in Fig. 9. This iece extends transversely across the face of the head 68 and is so formed as to provide two inward] extending terminal portions 79 and 80 which bear against the face of the head 68 and which are perforated for the passage of bolts 81 which hold the bridge piece in place. The body of the bridge piece extends downward, as at 82, so as to bear against the face of the rod 71 and is also provided with a lateral flange 83 defining a space or chamber 84 within which is pivotally mounted the pawl 85. This pawl 85 has a tooth 86, and on the inner face of the tooth is a rounded portion 87. The tooth has a thickness equal to the thickness of the toothed ratchet bar, but the rounded portion bears against the face of the bar 69, as illustrated in Fig. 2. The pawl is forced with its tooth into engagement with the ratchet teeth on the bar 71, by means of a spring 88 mounted within the chamber 84. Above the bridge piece 78 and resting thereon is a friction block 89 which is attached to the upper end of a spring 90 which extends down and at its lower end is fastened to the outer face of the body portion of the bridge piece. The face of this block 89, which is preferably of brass or like metal, is resiliently forced against the face of the rod 71 and not only frict-ionally engages this rod but resiliently forces this red and the rod 69 into frictional engagement with the face of the head 68. The lower end of the rod 69 is enlarged or widened and formed with the outwardly projecting lug 70, as previously stated, this lug 70 projecting immediately behind the rear edge of the rod 71. The upper end of the rod 69 is also widened, as at 91, and formed with the outwardly projecting rib or lug 92 which normally rests upon the upper edge face of the member 93 and .which is also disposed behind the rod 71, as shown in Figs. 5 and 2.

Attached to the late 49 by means of bolts is the bar 93 wliich is cut awa to permit the passage of a cam bar 94. hisbar 94 is held in place by means of a screw 95 which prevents any vertical movement of the bar. The lower end of the bar is angularly turned, as at 96, and passing through this ear 96 is a bolt 97 which passes through a slot 98 in an angle'plate 99 attached to the upper face of the plate 19. Thus the cam bar 94 is held ri 'dly in position, but it may be adjusted wit relation to the rods 69 and 71. This cam bar is formed upon its forward edge with an outwardl jecting lug 100 the lower edge of w ie is beveled as at 101. The u per end of the cam bar 94 is enlarged and the lower edge of this enlargement is beveled as at 102. The edge 101 coacts with the beveled edge 103 of the enlarged portion of the rod 69, and the beveled edge 102 coacts with the upper end of the lug 92.

When now the cross head or slide 50 rises the tooth 86 will engage with one of the ratchet teeth on the bar 71 and the bar 71 together with the bar 69 will be lifted with the cross head 50 until such position is.

reached that the beveled edge 91 engages with the beveled edge 101' on the cam bar 94, whereupon the bar 69, which is a pawl tripping device, will be shifted outward and engaging the rounded edge 87 of the pawl will force the pawl 86 out of engagement with the tooth on rod 71. As a consequence the cross head will now rise without affecting the rod 71 or its companion rod 69. There is suflicient frictional engagement between the rods 71 and 69 and the cross head to permit the rods 61 and 71 to travel upward with thecross head, were it not that the beveled edge 102 on the upper end of the cam rod 94 engages with the beveled flange 92 and stops the u ward movement of the rods. Thereafter he cross head 50 or slide travels upward by itself without carrying with it either the rod 69 or 71. Upon the initial downward movement of the cross head the frictional engagement between the rods 69 and 71 and the portion 68 will cause the rods 69 and 71 to move downward with the cross head until a position is reached where the lug 70 will engage with the upper face of the yoke 55. This will stop the descent of the rods 69 and 71 and the cross head will continue its descent. It will be seen from this construction that the initial movement of the car, skip or cage from a definite starting point, as, for instance, the top of the shaft, will cause a forward movement of the wheel 26 one step and that after this has been accomplished the cage will continue its downward movement to any position within the shaft without further affecting the wheel 23. The cage may stop at a certain level and then continue its movement farther downward, but it will not again turn the wheel 23. The cage must come back to its initial osition and again start out upon its travel fore the wheel 26 will be step ed forward. Thus the wheel 23 will step orward only upon a complete journey of the cage or car from the point of starting which will include a movement of the car away from the point of starting and back again to the startin point.

The mec anism is so arranged that only a, relatively short movement of the car or cage from the starting point is necessary to move the rod 71 asufiicient distance to actuate the pawl carrier and step the wheel 23 one step. After that it does not matter how inany times the elevator stops and starts, the wheel 26 will not be actuated until the car or cage has returned to' the starting point and is again started. It will be seen also that if the car or cage runs the full length of the shaft the cross head or slide 50 will be raised a dist-ancecorresponding to the travel of the elevator to the point where it returns. If the car or cage woes the full distance of the shaft, a vertical line will be made u on the recording sheet on the cylinder 28 which will extend nearly the full width of the recording sheet. If, however, the car goes, say, half way down the shaft, stops at a level and returns, the line drawn upon the recording sheet will only be onehalf the width of the record surface of the sheet, and the same applies: of course if the-elevator goes only a quarter the distance of the depth of the shaft. The line drawn upon the paper and indicating the movement of the elevator will always be proportionate to the full travel of the elevator so that the lines will indicate not only the number of movements that the elevator car or cage has made, but also whether the car on one trip traveled the full length of the shaft or only a portion of that length before returning to the starting point. Inasmuch as the movement of the cylinder 28 is very slight, the lines drawn u on the face of the recording sheet and in icating each a trip of the elevator will be very close together and therefore hard to count. For the purpose of providing indications marking every tenth trip of the car or cage, I provide the face of the wheel 26 with upwardly projecting lugs 104. These are arranged radially and disposed upon the pcripheral margin of the wheel 26. Mounted upon one edge of the plate 19 and projecting over the exposed portion ofthe wheel 20 IS, a bracket 105 which is perforated at its outer end for the passage of a verticallydisposed plunger 106. This plunger at its lower end' carries a roller 107 which is 'adapted to be engaged by the lugs 104. The upper end of a plunger is,formed with a head 108 which engages with the lever 109 pivoted between upwardly projecting ears 110 carried on "the bracket 105.

The inner end of this lever is 1" reduced as at 111 and extends through a perforation formed in the outer end of an arm 112, this arm at its inner end being pivoted at 113 to a supporting rod 114. Th'is'suppivoted to this arm 112 just forward of its pivotal point 113 is the lower end of a rod 117. The upper end'of this rod is linked to the rod 114 by means of the pivot link 118,

and connected to the upper end of the rod is the coilspring 119 which is attached at its upper end to the strip 22. The spring at its upper end acts to raise the rod 117 and hold it In this raised position. When, however, the roller 107 on the lower end of the plunger 106 strikes 'oneof 'the beveled lugs 104,

low the *stylus 53 is a sliding stylus shank 120 which at its outer end has the ears 121 in which is pivoted the stylus roller 122. The rear ends of this stylus shank abuts against the rod 117 so'that when the rod 117 is depressed and moves toward the recording cylinder, it will act to force the sliding stylus shank outward and force the stylus 122 into engagement with the recording sheet. Inasmuch as the stylus 122 is below the stylus 53, it is obvious that it will merely continue the mark made by the stylus 53 below or toward the lower edge of the recording sheet. Theslide 120 is slotted for the accommodation of a spring 123 which acts to return the'slide 120 to its original position. As sho'wn'in Fig. 7, the ears 121 are pivoted within the stylus shank 120 and a spring acts to yieldingly force these ears outward. When the stylus 122 strikes the recording sheet, these pivoted cars will yield inward so thattoo mucli'pressure will not bebrought to bear against the recording sheet which will act to tear it. I

The lugs 104 are preferably arranged coincidently with every tenth tooth of the wheel 26 so that upon each tenth trip of the car or skip, one of the -lugs 104 will engage with the plunger 106 and cause the projection of the stylus 122.

- ment of the elevatorca'r causes the upwa d movement of the stylus. As will be Se :1 from this record, and counting from t.

left hand end o'f the record, the car or sap made about four trips from the bottom of the shaft to a. level half way the length of the shaft. It then made about three trips from the top of the shaft to a point seveneighths of the distance of the shaft and then made nine trips the full length of the shaft, etc. It will be seen that with every tenth trip of the car or skip the auxiliary stylus 122 marked a line extending below the base I), this line being designated a. In Fig. 8, lines are drawn relatively wide apart so as 10 to be distinct, but in the actual record the lines are drawn so closely together that it is most convenient to have a means for indicating every tenth trip of the car or cage.

It is often necessary to rovide means for showing not only the num er of trips made by an elevator within a certain length of time, butalso showing the periods during which the elevator is at work and at rest so that the amount of work done by a hoistin apparatus or elevator may be determine It is for this purpose that I provide the time recording drum 43. Upon the exterior of this drum is fastened, as previously described, a strip of recording aper divided ;by vertical lines indicating time divisions and horizontal lines indicating the different levels or stages of the mine or structure within which the elevator or cage is used. Such a trip is shown in Fig. 3, wherein the ;vertical lines indicating time are designated d and,the horizontal lines indicating the stages or levels of the mine or other structure are designated e. This strip is shown as marked off into hours and half-hours by '35 the vertical lines 0!, and the record is supposed to be begun at 7.30 a. m. at the right hand corner of the end of the strip. The record consists of a line drawn in ink. Where the elevator is at rest the line will be 40 horizontal and where the elevator is traveling the line is vertical.

A line extending from the base line indicates a trip of the elevator, car or skip from the surface downward into the shaft and 46 back again, and it is obvious that the character of this line will indicate the relative speed of the elevator, its delay at various levels, and in fact the histor of each trip from the to of the shaft 50 shaft and ack again. The mechanism whereby this record is secured is as follows. Dependin from the cross bar 22 and rigidly attac ed thereto is a strip 124. The downwardly extending terminal portion of this strip carries a block 125 the side edges of which have undercut grooves cut in to it to form a guide. Pivotally mounted upon the plate 19 is a lever 126 having two arms extendin at an acute angle to each other.

One of t e arms extends upward at an incline to the vertical and is longitudinally slotted as at 127. A pin upon the slide or cross head 50 engages in the Slot :27. and it is obvious that as the slide or on ss head rises the lever 126 will be moved from a po own into the sition where the arm 126" is inclined, to a position where this arm is approximately vertical, and the arm 126 of the arm 126 will be raised under these circumstances, so that as the slide is raised the arm 126 is raised and as the slide is lowered the arm 126" is lowered. Attached to the extremity of the arm 126 and extending upward therefrom is a connecting rod 129 which at its upper end is connected to a slide 130. This slide is bifurcated so as to provide parallel, upwardly extending members 131 having angular inner faces which engage in the dovetailed grooves formed in the outer side edges of the member 125. This slide carries attached to 0 it an upwardly projecting arm 132 preferably in the form of a light spring. This arm at its upper end carries a pen 133 so formed as to retain a suflicient quantity of writing fluid such as red ink. As the rod 17 rises, carrying with it the slide or cross head 50 the slide 130 will also be raised carrying with it the pen 133, and this pen being in contact with the recording sheet, a mark will be made upon the recording sheet. As the drum carrying the recording sheet is traveling forward under the impulse of the clock mechanism, it is obvious that a time record of the actuation of the car, skip or cage will be made. It is also obvious that if the elevator, car or cage goes to the bottom of the shaft or to any other point within the shaft and stays there for any length of time, the record sheet will pass horizontally across thepen point 133 and a horizontal line will be made. It is to be noted that the record sheet 46 u on which the time record is made is relative y narrow and it is for this reason that I have provided the means illustrated for indirectly transmitting the movement of 106 the slide or cross head 50 to the pen 133 in place of directly connecting the pen to the cross head. The use of the angular armed lever 126 secures a proportionate but relatively small movement of the pen 133 upon 110 each reciprocation of the slide or cross head.

It is pointed out that the mechanism for advancing the large gear 26 is so constructed that no matter from which point the cage or car may start back, the pawl carrier is re- Ill leased to return. This is to take care of any irre larit that might take place in the win ing 0 the engine. Of course, there is a limit that must be considered, and the cage or car will have to travel at least twenty-five feet in the shaft before a record of that travel can be made. Of course, as all shafts are far deeper than this, anything less than twenty-five feet will not be worth recording.

It will also be noticed that the time record 128 sheet 46 faithfully charts what may be termed the events of each trip of the car the time it started, where it stopped, how long it stopped, whether it went out again, and when it returned to the starting point. 130

Inasmuch as it is diflicult to count the tri s upon the time record sheet, it is especial y convenient that when the trips are made rapidly and in close succession I have provided the mechanism recorder which makes the counting of the trips simple.

\Vhile I have heretofore described my recording device as being connected to hoisting machinery, it is equally applicable to the counting of cars passing over a track and is particularly useful for counting mining cars. \Vhile the recording mechanism is the same as that previously described, the means for actuating the recording mechanism will of course be different.

Fig. 11 shows my mechanism as attached to a track for recording the passage of cars. In this figure, C designates a rail of an ordinary railway track and 135 designates a movable rail which is so mounted that it normally projects above the face of the rail C and in position to be engaged by the tread of a car wheel. This rail 135 is of a length equal to the wheel base of the car. Disposed opposite to the track is a foundation plate or base 136 which has the upwardly projecting ears 137 between which is mounted the weight lever 138. The long arm of this lever extends outward and is provided with a shifting weight which may be in any desired position upon the arm. Mounted upon the ties which support the rail C and at opposite ends of the rail 135 are the ears 139 and attached to the opposite ends of the rail 135 are the levers 140. These are pivoted to the projecting ears 139 and then converge as at 141 and are connected at their converging ends by means of a link 142 to the lever 138 between the fulcrum 137 and the weight. The short arm of the lever is connected by means of a link 143 to a lever 144 fulcrumed upon the upwardly rojecting standard 145. The opposite end of the lever 144 is pivotally connected to the rod 17 of the recording mechanism, as previously described. The recording mechanism is recisely the same as that previously descri (1 except in three particulars. The time ac tuatcd recorder is removed and in place of the ratchet toothed rod 71 and the rod 69 only one cam rod is used, as illustrated in Fig. 10, this rod being designated 146. The rod 146 at its lower end is enlarged as at 147 and formed with a cam ed e 148 which engages with the roller 76 of t e pawl carrier The upper portion of the rod 146 is perfectly plain, that is, it is not provided with teeth, and it is clamped rigidly to the face of the cross head 50 so that it moves positively therewith. Inasmuch as the travel of the rod 17 will be the same at all times where-the device is used as a car counter, there is no necessity of providing the mechanism previously described whereby only the initial travel of the cross head 50 acts to shift the pawl carrier. Furthermore, by substituting the rod 146 for the rod 71 the extra jerks due to the momentum of rapidly passing cars are taken care of, as when the gear is once advanced the rod 146 can travel up or down to a considerable distance without communicating any further motion to the advancing gear. The third change above referred to is in the position of the top rolling disk pen or stylus designated 53 in Fig. 3.

Where the device is to be used for recording the passage of cars it is not desirable that a line of ull length should be recorded upon the recording sheet, and for that reason I change the position of the top stylus roller designated 53 in Fig. 3. As illustrated in Fig. 2, this upper stylus 52 is mounted in a slot 149 and is slidable outward in this slot or chamber within which it is contained. This stylus or roller carrier 52 has a laterally projecting pin 150 projecting out through a slot in the side plate which closes in the side of the projecting end of the stylus carrier 50 as illustrated in Fig. 7. Both sides of the casing within which the stylus 52 are mounted are provided with this slot and if the stylus 52 be reversed, that is, turned upside down, it will be seen that the pin 150 which normally projects out on the left hand side of the carrier 50 will be projected out on the right hand side of the carrier into contact with a vertical guide 151 which is supported in any suitable manner u on the plate 19. This guide has a straight face for a greater portion of its length but is cut away at 152. When in the reciprocation of the carrier 50 the pin 150 reaches this cutaway portion 152, it will be forced inward bringing the stylus roller in contact with the recording sheet. Above and below this cutaway partv 152, however, the flat inner face of the guide 151 will bear against the pin 150 and will hold the stylus carrier inward with its stylus wheel or roller away from the recording sheet. Thus only a relatively short record mark will be made upon the sheet for each reciprocation of the stylus carrier 50. If it were not for this, the lines would be very irregular owing to difference in momentum of cars passing over the rail 135.

While I have illustrated what I believe to be the best form of my invention, I do not wish to be limited thereto, as it is obvious that many changes may be made in the details of construction and arrangement of parts without departing from the spirit of the invention.

While I have shown my counting and recording mechanism as applied to elevators and as applied to railways, I wish it distinctly understood that it might be used in other situations without changing the principle of its construction.
